• Large Field of View
• C and CS-Mount Lenses
Varifocal lenses provide a flexible solution to applications that previously would have required multiple fixed
focal length lenses. Simply adjust through the indicated focal length range for the desired field of view, within
the specified working distance range, and then set focus for best image. They have a different, simplified optical
and mechanical design that is more cost-efficient to produce than zoom lenses.
Note: CS-Mount lenses are not compatible with C-Mount cameras.

• Low Distortion and Day/Night Options
• Focal Lengths from 4,4 mm to 90 mm
• C-Mount Lenses
Megapixel Varifocal Lenses are the ideal choice when you need a specific field of view that corresponds
to a non-standard focal length. They make system integration straightforward while allowing for fine tuning,
and also create the flexibility so the lenses can be integrated across multiple applications. Day/Night
varifocal lenses are the perfect choice when you need to extend your imaging system into the NIR without
sacrificing visible imaging.

• Versatile and Affordable
• Smaller Fields of View & Working Distances than Fixed FL Lenses
• Manual Iris for Light Control
Close Focus Zoom Lenses are ideal for inspection, documentation and testing applications. Due to their large
field of view range, these lenses are generally considered the best selection for multi-purpose use.
